摘要: 该试验以马铃薯克新1号为材料,研究不同灌水处理对马铃薯生理特性的影响。结果表明:苗期不灌水SOD、POD活性高,游离脯氨酸、可溶性蛋白含量高,可以增强植株的抗旱性。块茎形成、膨大期灌水,SOD、POD活性提高,可溶性蛋白,MDA、游离脯氨酸增加量降低,能够促进马铃薯生长。成熟期灌水对生理特性无显著影响。

Abstract: In this experiment, using Kexin 1 as the material,the effects of different irrigation treatment on the physiological characteristics of potato were studied. The results showed that no irrigation at seedling stage, the activity of SOD, POD was high and the contents of free proline and soluble protein was also high, which can enhance the drought resistance of plants.With the irrigation at tuber formation,expanding stage, the activity of SOD,POD were increased, the content of soluble protein were increased and the increment of MDA and free proline decreased, which can promote the growth of potato.Irrigation at mature stage had no significant effect on physiological characteristics.
